Christmas music...?

Question:

Christmas music...?

So at church I've been asked to perform a christmas piece on my violin. Does anyone know of a higher-level solo piece that preferably doesn't require accompaniment?
Please nothing too long, and would be easy for me to find the sheet music for. Thanks =)
